Junior guard Caroline Durbin put up a three-pointer with 12 second left rattled out. Pepperdine's Lauren Bell sealed the win with a pair of free throws with five seconds left.
New Mexico (2-4) played without junior forward Deeva Vaughn for the entire game, lost guard Nikki Nelson for the entire second half due to a first-half leg injury, and played without Lauren Taylor for most of the second half and overtime.
"In overtime, we just kind of got a little tired," senior forward Porche Torrance said. "We didn't have a lot of rotation on the floor with Deeva being out."
"It's hard with limited players," Sanchez said. "We wanted to try and win that in regulation and that didn't work."
Durbin and Torrance lead all scorers with 16 points and Jackson added 14 points. Torrance managed a double-double pulling in 15 rebounds. Junior guard Jourdan Erskine pulled in 10 rebounds for UNM. Pepperdine was paced by Shay Cooney-Williams, who scored 13 points.
UNM lead 36-28 at halftime after hitting 12-of-28 (43%) from the field, including three three-pointers and going 9-for-9 from the free throw line. The Lobos trailed 2-0 early but New Mexico went on a 10-2 run to take a 10-4 lead five minutes into the game.
The Lobos were able to control the pace of the game and brushed off a surge midway through the half. Pepperdine cut the lead to 24-22 on a trey by Lauren Bell with 6:40 left in the half. But UNM closed the half with a 12-6 run to take the halftime lead.
The Waves started the second half on a 5-0 run to cut the Lobo lead to 36-33 but UNM responded with a 9-0 run to take a 42-33 lead with just over 12 minutes left in regulation. Pepperdine made another run to cut the lead to 42-40 with nine minutes left. UNM resonded with an 8-0 run to set up the final sequence.
Unfortunately the Lobos shooting touch abandoned them in the final four minutes, as UNM made just 1-of-7 from the field and turned the ball over three times to fuel the comeback by the Waves.
"They were putting pressure on toward the end of the game, before we went into overtime," Torrance said. "I just think we kind of got a little rattled up and lost our focus a little bit,"
Pepperdine's bench outscored UNM's 16 to 6 and the Waves scored 17 points off turnovers compared to 12 for the Lobos – including four points in the crucial overtime period.
The Lobo women return to the court next Thursday, Dec. 1 at 7 p.m. against Loyola Marymount and host in-state rivals New Mexico State on Sunday, Dec. 4 at 1 p.m.
